DETAILED DESCRIPTION

Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of embodiment and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.

FIGS. 1-24 illustrate a modular garage door system 50 including a garage door opener 100 operatively coupled to a garage door 104. The garage door opener 100 is configured to interchangably receive a variety of accessory devices 200 such as a battery charger 204/battery pack 208, a speaker 212, a fan 216, an extension cord reel 220, an environmental sensor 224, a park-assist laser 228, a folding light 232, a retractable area light 236, and an inflator cord reel 240, via common coupling features on both the garage door opener 100 and accessory devices 200. Accordingly, a user can attach desired accessory devices 200 to any location on the garage door opener 100, remove unwanted accessory devices 200, and organize/relocate accessory devices 200 on the garage door opener 100 as desired.

The garage door system 50 may be operated by a wall-mounted keypad 244, a passcode keypad 248, and/or a peripheral device 252 (e.g., a smartphone based application, etc.). In the illustrated embodiment, the garage door opener 100 is configured to be coupled directly to an AC power source, and optionally use the battery 208 as back-up power source when AC power is unavailable.

With reference to FIGS. 1-5, the garage door opener 100 includes a housing 108 supporting a motor 112 (e.g., a 2 HP electric motor) that is operatively coupled to a drive mechanism 116. The drive mechanism 116 includes transmission coupling the motor to a drive chain 120 having a shuttle 124 configured to be displaced along a rail assembly 128 upon actuation of the motor 112. The shuttle 124 may be selectively coupled to a trolley 132 that is slidable along the rail assembly 128 and coupled to the door 104 via an arm member.

With continued reference to FIGS. 1-5, the trolley 132 is releaseably coupled to the shuttle 124 such that the garage door system 50 is operable in a powered mode and a manual mode. In the powered mode, the trolley 132 is coupled to the shuttle 124 and the motor 112 is selectively driven in response to actuation by a user. As the motor 112 is driven, the drive chain 120 is driven by the motor 112 along the rail assembly 128 to displace the shuttle 124 (and therefore the trolley 132) thereby opening or closing the garage door 104. In the manual mode, the trolley 132 is decoupled from the shuttle 124 such that a user may manually operate the garage door 104 to open or close without resistance from the motor 112. The trolley 132 may be decoupled, for example, when a user applies a force to a release cord 136 to disengage the trolley 132 from the shuttle 124.

In another embodiment, the drive mechanism 116 includes a transmission coupling the motor 112 to a drive belt that is operatively coupled to the garage door 104 via a rail and carriage assembly. The rail and carriage assembly includes a rail that is coupled to the main housing and a surface above the garage door opener 100 (e.g., a garage ceiling) and supports a trolley coupled to the drive belt. The trolley includes an inner trolley member and an outer trolley member. The inner trolley member is coupled to and driven by the belt, and the outer trolley member is coupled to the garage door (e.g., via a bracket).

The inner trolley member and the outer trolley member are releasably coupled to one another such that the garage door system 50 is operable in a powered mode and a manual mode. In the powered mode, the inner trolley is coupled to the outer trolley and the motor 112 is selectively driven in response to actuation by a user. As the motor 112 is driven, the belt is driven by the motor 112 along the rail to displace the trolley thereby opening or closing the garage door 104. In the manual mode, the outer trolley is decoupled from the inner trolley such that a user may manually operate the garage door 104 to open or close without resistance from the motor 112.

FIGS. 2-4 illustrate the garage door opener 100, which includes the housing 108 supporting the motor 112. The housing 108 is encased by an upper cover 140 and a lower cover 144, and by four sidewalls 146 extending between the upper cover 140 and the lower cover 144. The upper cover 140 is coupled to the rail assembly 128 and the surface above the garage door (e.g., the garage ceiling) by, for example, a support bracket 148. In the illustrated embodiment, the lower cover 144 supports a light 152 (e.g., one or more LED lights), enclosed by a transparent cover or lens 156, which provides light to the garage. The light 152 may either be selectively actuated by a user or automatically powered upon actuation of the garage door opener 100. In one example, the light 152 may be configured to remain powered for a predetermined amount of time after actuation of the garage door opener 100.

With reference to FIGS. 3 and 4, the housing 108 includes accessory ports 162 that receive and support modular, interchangeable accessory devices 200. In the illustrated embodiment, the housing 108 has eight accessory ports 162 with two ports 162 disposed on each side of the housing 108. However, this configuration is merely exemplary—that is, the housing 108 may include more than eight ports 162 or less than eight ports 162, and each side of the housing 108 may include more or less than two ports 162. Additionally, the housing 108 may include more or less than four sides with each having one or more ports 162, and other surfaces of the housing (e.g., the top and bottom) may include one or more ports 162.

With continued reference to FIGS. 3 and 4, each port 162 includes a communication interface 166 and a coupling interface 170. The communication interface 166 includes an electrical connector 174 disposed within a recess 178. The electrical connector 174 is configured to facilitate electrical communication and data communication between the accessory device 200 and the garage door opener 100. The electrical connector 174 may be any type of powered input/output port. Additionally, in further embodiments the electrical connector 174 may define separate power connectors and data connectors, which may similarly be any type of power connectors and data connectors.

In the illustrated embodiment, the coupling interface 170 includes two slots 182 formed on either side of the electrical connector 174, which receive a portion of an accessory device 200 to align and mechanically couple the accessory device 200 with housing 108. The coupling interface 170 further includes a pair of spaced apart, raised surfaces 186 defined on either side of the communication interface 166. Each raised surface 186 includes a chamfered edge and has an aperture 190 defined there through. However, the raised surfaces 186 may be omitted in other embodiments. The apertures 190 are configured to receive portions of the accessory devices 200 to further facilitate mechanical coupling of the accessory device 200 to the garage door opener 100.

In the illustrated embodiment, the housing 108 includes an electrical outlet 194 disposed between ports 162 on one or more sides of the housing 108 (FIG. 3). The electrical outlet 194 is a standard U.S. three-prong female AC plug 194 defined within a recess 198. However, the electrical outlet 194 may be any type of AC or DC electrical outlet. Furthermore, in the illustrated embodiment, one port 162 is omitted such that that a portion of the housing includes a customized port 164 for permanently receiving a specific accessory device 200 (e.g., a battery charging port) (FIG. 4). This type of customized port 164 may also be used in place of other ports 162 in other embodiments.

With reference to FIGS. 2 and 5, the garage door opener 100 receives a variety of different accessory devices 200 within the ports 162. In the illustrated examples, two ports 162 and the electrical outlet 194 receive the extension cord reel 220 on one side of the housing 108. On another side of the housing 108, one port 162 receives the environmental sensor 224 and the other port 162 receives the park-assist laser 228. On yet another side, one port 162 receives the fan 216 and the other port 162 is unused and blocked by a cover 256. The final side includes one of the ports 162 and the customized port 164, where the port 162 receives the speaker 212 and the customized port 164 supports the battery charger 204 for receiving a battery pack 208 (e.g., a power tool battery pack). Each accessory device 200 will be described in greater detail below with reference to FIGS. 8-19.

Additionally, the garage door opener 100 includes a controller 201 having an electronic processor and a memory. The electronic processor is configured to execute instructions stored on the memory to carry out control functions of the garage door opener 100 described herein. For example, the controller 201 is configured to one or more of control driving of the motor 112, control the enabling and disabling of the light 152, communicate with the accessory devices 200, and control the power to the accessory devices 200, as described in further detail below.

FIGS. 6 and 7 illustrate the battery charger 204 disposed on the housing. In the illustrated embodiment, the battery charger 204 includes a charging port 260 including electrical contacts configured to transfer electrical charge from the garage door opener 100 to the battery pack 208. Additionally, the charging port 260 includes a mechanical coupling mechanism 264 to engage and retain the battery pack 208 within the charger. The mechanical coupling mechanism 264 may be any conventional battery pack coupling mechanism, such as those used in battery chargers and/or power tools.

The battery charger 204 further includes a door 268 pivotally coupled to a side of the battery charger 204 via a hinged connection 272 such that the door 268 is movable between a closed position (FIG. 6) and an open position (FIG. 7). The door 268 is configured to cover the battery charger 204 when a battery pack 208 is not connected. Additionally, the door 268 is sized and shaped to enclose a battery pack 208 received within the charger 204. The door 268 is retained in a closed position by a locking mechanism 276 defined by a press fit detent; however, other locking mechanisms may be used.

When a battery pack 208 is coupled to the battery charger 204, the battery pack 208 also provides power to the garage door opener 100 when the garage door opener 100 loses power—that is, the battery pack 208 serves as a ‘DC battery back up.’ The garage door opener 100 is configured to detect loss of power (e.g., upon a power outage at AC power source 209 (FIG. 5)) and reconfigure the battery charger 204 to receive power from the battery pack 208 when power is lost. In this way, even when the garage door system 50 loses external power, the garage door opener 100 is still able operate the garage door 104.

In one embodiment, the garage door opener 100 monitors a voltage of the battery pack 208 (e.g., at continuous intervals, continuously, etc.) when the battery pack 208 is connected to the charger 204. If the voltage is below a predetermined level, the charger is configured to charge the battery. Once the voltage of the battery reaches the predetermined level, the charger is configured to cease charging operations (e.g., via the use of a relay). In the case where AC power is lost, and the battery pack 208 is used as a battery back up to power the garage door opener 100, the battery pack 208 is operatively connected to the garage door opener 100 to power the motor 112 (e.g., via a relay activated by the loss of AC power). For example, as illustratd in FIG. 5, the garage door opener 100 may include a power supply 211 that is electrically coupled to the AC power supply 209 and to the battery pack 208 (via the port 164 and the battery charger 204). The power supply 211 may be further coupled to and provide power to the motor 112, light 152, other internal circuitry of the garage door opener 100, and the other accessory ports 162 to power any coupled accessory devices 200.

FIGS. 8 and 9 illustrate the accessory speaker 212 configured to be detachably coupled to the garage door opener 100. In the illustrated embodiment, the speaker 212 is a wireless speaker 212 (e.g., a Bluetooth® speaker) that may be wirelessly coupled to a peripheral device 252. In one embodiment, the speaker 212 receives an audio stream from a peripheral device 252 communicating with the garage door opener 100, and subsequently drives a speaker 212 to output the audio stream using power from the garage door opener 100 via the electrical mounting interface 400. In another embodiment, the wireless speaker 212 receives an audio stream wirelessly directly from a peripheral device 252 via an integral transceiver, and drives a speaker 212 to output the audio stream using power from the garage door opener 100 via the electrical mounting interface 400.

With reference to FIG. 9, the speaker 212 includes a mechanical mounting interface 300 configured to be coupled to the coupling interface 170 of the housing 108, and an electrical mounting interface 400 configured to be coupled to the communication interface 166 of the housing 108. The mechanical mounting interface 300 includes a pair of hooks 304 that are received within the apertures 190 of the coupling interface 170, a pair of projections 308 disposed on opposing sides of the electrical mounting interface 400, and at least one protruding latch member 312 configured to engage a corresponding retention member on the housing 108. The projections 308 are configured to be received within the slots 182 to assist with alignment of the electrical mounting interface 400 and the communication interface 166. When coupled, the speaker 212 receives power from the garage door opener 100 via connection between the electrical mounting interface 400 and the communication interface 166. The speaker 212 also sends and receives data from the garage door opener 100 via connection between the electrical mounting interface 400 and the communication interface 166.

With reference to FIGS. 10 and 11, the accessory fan 216 includes a mounting member 280 supporting a rotatable and pivotal yoke 284 having a fan 288 pivotally retained between a pair opposed arms 292 (i.e., the fan is supported by a gimbal mount). As seen in FIG. 11, the mounting member 280 includes a mechanical mounting interface 300 and an electrical mounting interface 400 that are substantially similar to the interfaces described above with reference to FIGS. 8 and 9. The interfaces 300, 400 engage the housing 108 in a substantially similar matter as those described above with reference to FIGS. 8 and 9. The fan 216 includes a fan motor that drives fan blades based on power received from the garage door opener 100 via the electrical mounting interface 400.

With reference to FIGS. 12 and 13, the accessory retractable cord reel 220 includes an extension cord 222 having power outlet member 226 having power outlets 230 extending from an aperture 234 in a cylindrical main housing 238, with excess extension cord 222 being retained on a cord spooling mechanism (not shown) supported within the housing 238. In one embodiment, the cord spooling mechanism includes a rotatable plate for supporting the cord 222 that is biased by a spring (e.g., a torsion spring). The spring biases the rotatable plate to drive automatic spooling of the cord 222. The cord spooling mechanism also includes a locking member that engages the rotatable plate to fix the rotatable plate into a position allowing the cord extend from the housing at a desired length. The locking member may include a user accessible actuator (e.g., a button, a switch, etc.) or an automatic mechanism. The automatic mechanism may, for example, be engaged when the cord is extended and subsequently released via the application of a first force, and then disengaged when a second force is applied to the cord. However, other spooling mechanisms may be used as well.

With reference to FIG. 13, the main housing 238 includes a mounting plate 242 extending across a rear surface of the main housing 238. The mounting plate 242 includes a mechanical mounting interface 500 defined by four hooks 504, two projections 508, and two latch members 512. The projections 508 are disposed on opposing sides of an electrical mounting interface 600 that includes a male AC plug or plug 604 (e.g., a standard three prong US plug, other standard AC plugs, standard DC plug, etc.). The male AC plug 604 extends from an end of a projecting member 608 that is sized and shaped to be received with the recess 198 of the housing 108. In addition, the AC plug 604 is a pivotable plug to facilitate the attachment between the retractable extension cord reel 220 and the garage door opener 100.

To connect the accessory retractable extension cord reel 220 to the garage door opener 100, the accessory retractable extension cord reel 220 is angled relative to the garage door opener 100 and the hooks 504 placed in four corresponding apertures 190 of two ports 162 on one side of the garage door opener 100. The accessory retractable extension cord reel 220 is then rotated to displace the plug 604 toward the housing 108 such that projecting member 608 is received within the recess 198 and the male AC plug 604 is received by the female AC outlet 194. To account for the pivoting of the accessory retractable extension cord reel 220 relative to the garage door opener 100 during connection, the male AC plug 604 pivots so as to maintain alignment with the corresponding electrical outlet 194 on the housing 108 so the prongs of the male AC plug 604 are properly received within the female outlet 198. In operation, electricity is transferred from the garage door opener 100 to the accessory retractable extension cord reel 220 via connection between the male AC plug 604 and the female AC outlet 198.

FIG. 14 illustrates the environmental sensor 224. In the illustrated embodiment, the environmental sensor 224 includes an air inlet 246, indicators 250 (e.g., LEDs), and a speaker 254. The air inlet 246 allows ambient air within the garage to enter the environmental sensor 224. Inside the sensor 224, the air is analyzed to determine the presence of carbon monoxide. The environmental sensor 224 provides an alert to a user within the garage. For example, one of the indicators 250 may be activated to indicate the presence of carbon monoxide within the garage and/or the speaker 254 is activated to sound an alarm. Furthermore, in some embodiments, the environmental sensor 224 communicates the presence of carbon monoxide to a peripheral device 252 (e.g., a cell phone, a computing device, one of the keypads, etc.) either directly or via the garage door opener 100.

Although the illustrated environmental sensor 224 is a carbon monoxide detector, other air characteristics may be analyzed in addition to or in place of carbon monoxide. For example, other air characteristics may include humidity, temperature, and the presence of other gases (e.g., smoke, etc.). In other embodiments, the environmental sensor 224 may include a display (e.g., LCD, etc.) for displaying air characteristics to the user.

The environmental sensor 224 includes a mechanical mounting interface 300 and an electrical mounting interface 400 on a rear surface (not shown) that are substantially similar to the interfaces described above with reference to FIGS. 8 and 9.

The modular garage door system 50 provides a garage door opener 100 that can receive a variety of accessory devices 200 in any combination for use with the garage door opener 100. The identical ports 162 located about the housing 108 allow accessory devices 200 to be located in multiple locations on the garage door opener 100 because each of the accessory devices 200 described in FIGS. 6-11 and 14-19 includes similar mechanical mounting interfaces 300 and electrical mounting interfaces 400 to engage each identical port 162. Accordingly, the accessory devices 200 can be removed, relocated, and replaced on the ports 162 of the garage door opener 100 as desired. Further, a user can determine which accessory devices 200 are best suited for their needs and personalize the system 50 by coupling preferred accessory devices 200 to the garage door opener 100 as needed. The system 50 allows many accessories commonly used within a garage to be attached and powered by a single power source via the garage door opener 100.

FIGS. 20 and 21 illustrate a pair of obstacle detection sensors 700 a, 700 b. As seen in FIG. 21, the obstacle detection sensors 700 a, 700 b are mounted on opposing sides of the garage door 104 in facing relation to one another. The obstacle detection sensors 700 a, 700 b include a transmitter (e.g., sensor 700 a) and a receiver (e.g., sensor 700 b), where the transmitter directs a beam of light (e.g., infrared light) toward the receiver. If the beam is interrupted (i.e., an object passes through the beam) during operation of the garage door 104, the obstacle sensor sends a signal to the garage door opener 100 to pause and/or reverse operation. The obstacle sensors 700 a, 700 b may communicate with the garage door opener 100 via a wired or wireless connection.

FIGS. 22 and 23 illustrate exemplary control devices for the garage door system 50. FIG. 22 illustrates a passcode keypad 248 including buttons.

The passcode keypad 248 may be placed on a surface that is outside of the garage, and operatively communicates with the garage door opener 100 via a wired or wireless connection (e.g., via radio frequency communication).

FIG. 23 illustrates a wall-mounted keypad 244 having buttons and a display. The buttons operate the door to open or close, as well as operate specific features of the garage door opener 100 (e.g., the light) or accessory devices 200. The display shows the status of the garage door as well as the status of accessory devices 200 coupled to the garage door opener 100. As seen in FIG. 23, the wall-mounted keypad 244 may be mounted to a wall within the garage, and operatively communicates with the garage door opener 100 via a wired or wireless connection (e.g., via radio frequency communication).

With reference to FIGS. 24 and 25, the garage door opener 100 includes a one or more transceivers 800 for communicating with peripheral devices 252. In one embodiment, the garage door opener 100 includes a first radio frequency transceiver 800 a in communication with the passcode keypad 248, the wall-mounted keypad 248, and one or more remotes (e.g., portable car remote controllers) and a second transceiver 800 b in communication with a network and/or one or more peripheral devices 252 (e.g., a smartphone or other computing device). The second transceiver 800 b communicates with the network and/or peripheral devices 252 via radio frequency communication, Wi-Fi communication, Bluetooth communication, or any other acceptable communication protocols. In another embodiment, the garage door opener 100 includes a single transceiver communicating with each of the peripheral devices 252.

Each of the first and second transceivers 800 a, 800 b is further in communication with a controller 804 disposed within the garage door opener 100. The transceivers 800 a, 800 b receive data and commands from their respective peripheral devices 252 and direct them to the controller 804, which further directs the data to appropriate components (e.g., the motor, light, etc.) or accessory devices 200 of the garage door opener 100. In addition, the controller 804 receives data and commands from the components and the accessory devices 200 coupled to the garage door opener 100, and subsequently directs the data and commands to the appropriate transceiver 800 a, 800 b in order to communicate the data and commands to the appropriate peripheral device 252.

In one example, one peripheral device is a smartphone 900 including a smartphone application for controlling the garage door system 50 (FIG. 25). The smartphone application includes a partitioned user interface 904, where each component/accessory device 200 of the garage door includes a partition of the interface 904. In one example, each partition includes a display 908 for showing the status of the component/accessory device 200 associated with the partition, as well as one or more actuators 912 for controlling the operation of each component/accessory device 200.

In operation, the garage door system 50 is operated by a user via one or more of the peripheral devices 252. A user may remotely actuate the garage door 104 to open or close. Additionally, the user may operate and monitor each accessory device 200 that is plugged into a port 162 of the housing 108 using one or more of the peripheral devices 252 via the operative communication between the electrical mounting interface 400 of each accessory device 200 and each communication interface 166 of the garage door opener 100.
